Original commit message from CVS:
Brand new source, the cdparanoia source.  Reads audio data from a CD,
writes out raw audio.  The tests/paranoia.c program will simply hook this
up to a sound card.  It works perfectly.

Next step is to flesh out the rest of the element, including pad caps,
better seek and playout control, signals, and whatever else comes up.

A minor patch to the editor is included here, the GstElementFactory details
struct has a name change from 'class' to 'klass' that wasn't reflected
in the elementselect widget.  Fixd.

Original commit message from CVS:
Changes made to the DEBUG system.  New header file gstdebug.h holds the
stuff to keep it out of gst.h's hair.  DEBUG prints out the process id,
cothread id, source filename and line number.  Two new macros DEBUG_ENTER
and DEBUG_LEAVE are used to show the entry and exit of a given function.
This eventually might be used to construct call trace graphs, even taking
cothreads into account.  This would be quite useful in visualizing the
scheduling mechanism.

Minor changes to various debug messages.

Also sitting in gstdebug.h is a prototypical DEBUG_ENTER that's capable of
performing DEBUG_LEAVE automatically.  It does this by utilizing a
little-known GCC extension that allows one to call a function with the
same parameters as the current function.  The macro uses this to basically
call itself.  A boolean is used to ensure that when it calls itself it
actually runs the body of the function.  In the meantime it prints stuff
out before and after the real function, as well as constructing a
debugging string.  This can be used eventually to provide call-wide data
on the DEBUG lines, instead of having to replicate data on each call to
DEBUG.  More research is needed into how this would most cleanly be fit
into some other chunk of code, like GStreamer (I think of this DEBUG trick
as a separate project, sorta).

Unfortunately, the aforementioned DEBUG trick interacts quite poorly with
cothreads.  Almost any time it's used in a function that has anything
remotely to do with a cothread context (as in, it runs in one), a segfault
results from the __builtin_apply call, which is the heart of the whole
thing.  If someone who really knows assembly could analyze the resulting
code to see what's really going on, we might find a way to fix either the
macro or the cothreads (I'm thinking that there's something we missed in
constructing the cothreads themselves) so this works in all cases.

In the meantime, please insert both DEBUG_ENTER and DEBUG_LEAVE in your
functions.  Be sure to put DEBUG_ENTER after your variable declarations
and before any functional code, not to put the function name in any DEBUG
strings (it's already there, trust me), and put a DEBUG_LEAVE if you care
enough.

Changes are going to happen in the way DEBUGs and other printouts occur,
so stay tuned.

Original commit message from CVS:
Reworked AC3 decoder. No seeking yet but at least we do not need ac3parse
anymore.
Reworked dvdsrc to read scrambled data (DeCSS not included). I have
modified DeCSS a bit to work in GStreamer. Can I release the code or is
there some lawyer that's going to sue me?
MPEG2 SSE motion compensation.
Tried to add PTS to the MPEG decoder but failed.

9bae9d4b91 More Docs updates.
Original commit message from CVS:
More Docs updates.
Added plugin documentation. I fear we need a gstdoc implementation
that loads plugins and does introspection on them. I think we should
automatically create the docs for the pads and mime types the plugins
provide. Does anyone have enough perl knowledge to add these features? I
allready changed the C code to output the pad definitions but my perl
knowledge is too limited, for now, to implement the rest of the needed
functionality...

Added building of the manual to the build system.  Currently in a
rudimentary state - will not gracefully give up if tools not available,
will not uninstall / clean, and may not install / make dist properly.
Documentation does not have dependencies on images, so won't rebuild if
they're altered either.

Original commit message from CVS:
Fixed a bug in the typeloading.
Fixes to various elements so that correct types are returned.
Fixed flag collision with GtkObject.
Elements can now suggest a thread. not sure if this is the right way to
handle automatic thread creation.
Autoplugging now works with multiple sinks and thread setup. No threads
are created for intermediate elements yet, so MPEG may still be choppy.

5a7cbafdda More work porting to PPC. libs/winloader is disabled on PPC - I doubt this can be made to work.
Original commit message from CVS:
More work porting to PPC.
libs/winloader is disabled on PPC - I doubt this can be made to work.
libs/videoscale and libs/idct are also disabled - they should be fixable
though.

Sorted out most of the plugins - avi is disabled for now on PPC;
can be worked on later if there's any chance of getting it to work.

Also provide an automake conditional for compiling vorbis, based on a
configure test for the needed libraries: currently the test isn't
implemented and defaults to "no" so you'll have to fiddle it to compile
vorbis.  I shall get hold of vorbis and implement an appropriate test some
other time (if noone else beats me to it).

Fix on x86 architectures - was just checking for 386, D'oh.

Original commit message from CVS:
Due to popular demand :-), I added a vorbis decoder.
The encoder is not yet functional.
Small cosmetic changes to gstcpu.c

Beware:
You *need* to install libvorbis.a from the main vorbis CVS.
you *have* to change the line in libtool to
deplibs_check_method="pass_all"
because else the plugin shared library refuses to link against the
static libvorbis.a library. This is a hack. I have no intention in
including libvorbis into the gstreamer CVS tree and making it
libtool compatible.

cf0a34528d libXv is now linked against by test/* and gstplay if it is present.
Original commit message from CVS:
libXv is now linked against by test/* and gstplay if it is present.
-lXv isn't leaked all over the place due to AC_CHECK_LIB test.
This is still messy though - we shouldn't have to link explicitly
with extra things just because we use certain plugins.

Build Makefile in tests, but don't recurse into tests when doing the
build  (tests no longer in SUBDIRS).
